Remove 4 fan shroud bolts.
Drain oil cooler.
Remove upper & lower oil hoses.
Remove transmission cooler lines.
Drain radiator.
Remove upper & lower coolant hoses.
Remove 2 "Rubber bands" if still intact.
Lift out radiator (may need a jack if stuck, with a 2x4 longways underneath to prevent damage to the radiator).
I'd rate it about a 3 in difficulty on a 1-10 scale. My Jeep is more difficult, probably a 5, & it's just the radiator that would come out (trans cooler is not attached to the rad, no oil cooler).
